WATER CUT-OFF.

To all whom it may concern:

Be it known that I, MINERVAJ. STEPHEN- nited States, residing at Seward, in the county of Seward, State of Nebraska, have invented certain new and useful Improvements in WVater Cut- Offs; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to water cut-ofis of that general class designed to permit of the escape of a predetermined amount of water through a conductor pipe from the eaves, and to automatically direct the stream into the cistern or other container after the first or polluted portion has escaped.

The object of this invention is to pro vide a simple and less expensive device of this character than hitherto obtainable and to so construct this device that the deflecting mechanism will be entirely concealed from view.

With the above and other objects in View, the invention consists of the novel details of construction, and combination of parts hereinafter fully described and claimed, it being understood that various modifications may be made in the minor details of construction within the scope of the appended claims.

In the accompanying drawings forming part of this specification: Figure l is a longitudinal sectional view of the device showing the deflecting mechanism in position for permitting the escape of the first portion of the stream. Fig. 2 is a longitudinal sectional view through the device showing the deflecting mechanism in position for directing the stream to the container. Fig. 3 is a longitudinal sectional view taken on the line 33, Fig. 1. Fig. 4 is a rear perspective view of the gate.

Referring now to the drawings, the reference character 11 designates the entering pipe, the upper end of which is fitted to the, conductor-pipe leading from the eaves, and

this entering pipe is provided at its lower,

end with a pair of inclined branches l2 and 13 adapted to direct the stream from the eaves to the cistern and upon the ground respectively. The pipe 12 leading to the cistern will be hereinafter referred to as the cistern pipe and the pipe 13 leading to the ground will be hereinafter referred to as the escape pipe. The escape pipe as will be Specification of Letters Patent.

end of this worm being provided with a reduced neck 15 which extends through the wall of the exhaust pipe, and is then provided with a rivet head 16 which retains the worm in position. worm terminates a short distance from the opposite wall of the discharge pipe and is disposed a slight distance above the horizontal plane of the open end of this pipe. Mounted upon the worm is a water wheel 17 having a tubular hub 18 which is threaded internally and travels along the worm. A rranged upon the hub are plate like blades 19, these blades being preferably four or six in number, although any desired number may be employed, and each blade is spaced from the hub by a pair of spaced spokes 20. It will be observed that the water wheel is free to rotate upon the shaft and when rotated in one direction will advance along the worm toward the free end of the latter which movement as will hereinafter appear is utilized in'opening a gate 21.

The gate 21 comprises a pair of curvilinear sections 22 and 23, these sections be ing hingedly connected together at their meeting straight edges in any desired manner, the preferred construction being to form adjacent each corner of one of the sections a pair of hinge lugs 24: and to form on the corresponding corner of the mating section a hinge lug 25 which fits between the The free end of the hinge lugs 24 and is connected to the latter nected at one end to the lower wall of the,

cistern pipe, this connection being effected by means of an ordinary butt hinge 27 one leg of which is fixed to the gate and the opposite leg of which is fixed to the side wall of the pipe. This hinge is preferably so mounted as to hold the lower section 22 of the gate in the position shown in Fig. 1 when the gate is in closed position, the section 22 in this position being inclined at an angle approximately 30 degrees to the bottom wall of the cistern pipe and the top flat edge of this plate being disposed in horizontal alinement with the outer edges of the paddle wheels 19. When the lower section is in the position above described, the upper section 22 will be inclined. oppositely to the lower section and will rest with its upper edges against the side wall of the en tering pipe 10. l/Vhen in this position of the parts, the stream flowing from the eaves will be directed through the entering pipe and discharge pipe since the mouth of the cistern pipe is sealed by the gate. Thus water when flowing through the discharge pipe actuates the water wheel.

For utilizing the advancing movement of the water wheel, an arcuate resilient finger 28 is fixed to the forward outer corner of one of the blades, the free end of this finger terminating approximately in alinement with the inner longitudinal edge of the water wheel. Fixed on the reverse face of the gate is an arcuate plate 29, this plate having upon one of its longitudinal edges a flange 30 through which and the lower section of the gate, bolts or similar connectors 31 are passed to rigidly secure the parts together. This plate is disposed to arch over the hingedly connected straight edges of the gate sections and when the gate is in closed position is disposed in horizontal alinement with the arcuate finger carried by the water wheel. As the water wheel advances upon the worm, the arcuate finger will be advanced into engagement with the arcuate plate and a further advancing movement of the water wheel serves to rock the sections of the gate open similar to a toggle lever, this opening movement of the sections causing the upper section to rock into engagement with the opposite wall of the entering pipe and per mit of the stream entering the cistern pipe. The advantage of employing an arcuate plate 31 is to minimize the jar on the gate as the water wheel advances into engagement therewith. For guiding the upper section 22 of the gate in its rocking movement, I provide a pair of guide pins 32 and 33 which project inwardly from one of the side walls of the entering pipe and engage the opposite sidefaces of the upper section of the gate. It will now be seen that when the water wheel advances into engagement with the gate that the upper section of the gate will be accurately rocked to its open posi tion, the stream of water operating to faciliter of the stand pipe so that the stream will be directed toward the side of the stand pipe opposite that side upon which the plate is fixed and will strike against the alter wheel disposed adjacent said side, thus operating to rotate the water wheel in the desired direction.

A hinged door 37 closes an opening 38 formed in one side of the entering pipe above the water wheel and permits the water wheel being rotated back to its initial position after each storm so that the gate may be manually set in operative or open position.

It will be noted that a device constructed as above described will be simple and inexpensive and further will have all its deflecting mechanism concealed "from view.

that is claimed is 1. A water out Oh? comprising an inlet pipe and branched discharge pipes connected therewith, a toggle gate normally directing the flow into one of said discharge pipes, and a water wheel adapted to engage and cause said toggle gate to move so as to direct the flow into the mating discharge pipe.

2. A water cut off comprising an inlet and a plurality of outlet pipes, a toggle gate adapted to be manually moved into a closed position whereby to direct the flow from the inlet pipe into one of the outlet pipes, a water wheel operating to move the gate to open position whereby to direct the How into the mating discharge pipe, and a baflie arranged in the inlet pipe and directing the How so as to cause the water wheel to retate in an operative direction.

In testimony whereof, I ai'liX my signature, in presence of two witnesses.
